COTTON-PICKING MACHINE.

Application filed May 9, 1814.

To aZZ whom it may concern Be it known that 1, JOHN MEIER, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Cotton-Picking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in cotton picking machines and it relates more particularly to that class of machines in which the picking is accomplished by suction produced by a rotary fan and it has for its obiect, among others, the provision of a machine of this character in which the cotton is received within the casing or fan chamber at a point above the point at which it is discharged.

The invention relates further to pneumatic suction fans for use in cotton picking machines and comprising means whereby the cotton and the seed as they are picked from the boll of the plant may be forcibly drawn through a casing without any danger of injuring the cotton or seed.

Another and an essential feature of the present invention consists in the provision of a casing having inlet and exit passageways leading thereto with a fan mounted eccentrically within the casing and so arranged that the size of the passageway through the casing will increase in width from the inlet to the exit ends thereof, thus reducing to a minimum the obstructions for the passage of the cotton as it passes through the casing.

A further and essential object of the invention resides in the provision of a machine of the character described in which the peripheral inner wall of the fan casing is provided throughout a portion of its distance with baffle pegs or projections extending inwardly and inclined slightly downward, the object of such pegs being to jar or break the bolls, thus permitting the escape therefrom of cotton which would otherwise be wasted.

To these ends and to such others as the invention may pertain, the same consists in Specification of Letters latent.

the novel construction and in the peculiar arrangement, combination and adaptation of parts, all as will be more fully hereinafter described, shown in the accompanying drawings and then specifically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification and in which drawings: Figure 1 is a side elevation of a cotton picking machine constructed in accordance with my invention. Fig. 2 is a central vertical section of the same. Fig. 3 is an edge view. Fig. 4 is a vertical transverse section of the machine. Fig. 5 is a detail view of the inside of the segmental plate carrying the baffle pegs. Fig. 6 is a detail in perspective of one of the fan plates, and Fig. 7 is a sectional perspective View of one of the side plates of the fan.

Reference now being had to the details of the drawings by numeral, 1 represents the fan chamber within which is provided a fan wheel 2 pivoted upon a central shaft 3, the ends of which shaft are suitably journaled within journal boxes 4 carried by a suitable supporting frame 5, the lower portion of which supporting frame is securely bolted to the floor 6 of the vehicle upon which the machine is mounted. Means are provided for the tilting of the chamber by the engagement of horizontal pins or projections 7 which extend outwardly from the lower edge of the side walls of the fan box and may engage elongated slots 8, provided in the legs or lower portion of the fan supporting frame. The fan wheel. is provided with radially disposed blades, each blade consisting of a metallic plate having its outer end 10 bent at right angles to the body of the plate, as shown clearly in Fig. 5 of the drawings. This plate is securely bolted at its lower edge to the collar or cylindrical portion 11 of the fan and to the outwardly extending flanged ends 10 of the plate are bolted the side plates 12.

Within the outer curved peripheral wall of the chamber 1 is provided a curved sectio'nal plate 18, the said plate being held in place Within the chamber by attachment to the curved angle irons 14 and the late is provided with a series of curved an down- 'w'ardly inclined baffle pegs or projections 15, these pegs being secured to the plate in any suitable manner as, for instance, by engagement of ,thejs'crew threaded shank. at, the.

lower end withthe screw-threaded openings formed in the plate, or they can be attached in-any' other suitable manner. The plates 13 are detachable and interchangeable so 'that-plates havingbaffle pegs of a-size suit-- able for the particular kind of wo'rk or class of work being, operated upon can be used and, nnder varying conditions, the plate can having, pegs-bestadaptedto the use for w ir have'in t drawings Stan rm,

Having thus described my invention, What .I claim to.b e,new and desire to secure by t af entri grl t A cotto boll opener and picker comprising a casing having a free inlet openingand a free outlet opening, one vertically above the'othenfl a cylinder mounted to rotate in casing, havingflanges at the ends thereof and blades between the flanges armin meet de h b c n fqrmin one side of the casing, teeth onthe concaveagainst and along which the cotton bolls are adapted to bev forced; by the fan, the cylinderbeing located. eccentri cally to the concave whereby the teeth near the inlet a i 'nearr the fan blades than the teeth ear he tlet' .v
